Explanation Calculation: It is given that the ceiling is 10 ft at the walls, 14 ft high at the center and the width of a hallway is 16 ft. Therefore, the point ( 6.00 , 4.00 ) on any of the parabolic cross sections. Draw a hallway which has a ceiling as shown below in Figure 1. From Figure 1, it is observed that the semi ellipse is centered at the origin and its major axis along x -axis. Therefore, the equation of the ellipse is x 2 a 2 + y 2 b 2 = 1 . Here, it is observed that the value of a = 16 2 and b = 14 − 10 . That is, a = 8 and b = 4 . The equation of the ellipse becomes x 2 8 2 + y 2 4 2 = 1 . The ceiling is 4 ft from each wall which means x = 4 . Find the value of y for x = 4

On Feb. 8, this year, at 6am in the morning all UiB meteorology professors met to discuss a highly unfortunate and top-urgent crisis: Their most precious instrument, responsible for measuring the air temperature hour-by- hour, had failed - what if the Bergen public would find out? How would they plan their weekend without up-to-date air temperature readings? Silent devastation - and maybe a hint of panic, also - hung in the room. Apprentice Taylor, who - as always - was late to the meeting, sensed that this was his chance to shine! Could they fake the data? At least for some hours (until the measurements would work again)? He used to spend a lot of time online and thus knew the value of fake data, especially when it spread fast! He reminded the crying professors of a prehistoric project with the title "Love your derivatives as you love yourself!" - back then, they had installed top-modern technology that not only measured the air temperature itself, but also its 1st, 2nd, 3rd, 4th, and…

Consider a forest where the population of a particular plant species grows exponentially. In a real-world scenario, we often deal with systems where the analytical function describing the phenomenon is not available. In such cases, numerical methods come in handy. For the sake of this task, however, you are provided with an analytical function so that you can compare the results of the numerical methods to some ground truth. The population P(t) of the plants at time t (in years) is given by the equation: P(t) = 200 0.03 t You are tasked with estimating the rate of change of the plant population at t = 5 years using numerical differentiation methods. First, compute the value of P'(t) at t = 5 analytically. Then, estimate P'(t) at t = 5 years using the following numerical differentiation methods: ⚫ forward difference method (2nd-order accurate) 3 ⚫ backward difference method (2nd-order accurate) ⚫ central difference method (2nd-order accurate) Use h = 0.5 as the step size and round all…
